UNITED STATES PATENT OFFIGEQ FRANK P. PFLEGHAR, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO ENGLISH & MERSICK, OF SAME PLACE.

COACH-HINGE.

SPECIFICATION formingpart of Letters Patent No. 244,293, dated July 12, 1881.

Application filed May 23, 1881. (N 0 model.)

To all whom it may concern Be it known that I, FRANK P. PFLEGHAR, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Coach-Door Hinges, of which the following is a specification.

The style of hinge which I have improved is that patented to C. E. Schwind, August 27, 1867, and known in the trade as a concealed hinge for coach-doors. The construction of this hinge is such as to allow the door to be mounted and to be removed without detaching the face-plate from the pillar of the coachbody byhavin g the pivot and slide part which carries it, forming the operative parts of the hinge, adapted for insertion and attachment through a vertical slot in said face-plate, so that a curved arm which connects the doorhinge part will operate within a horizontal slot in said faceplate with the opening and the closing of the coach-door. In the use of such a hinge the coach-body, with its pillar-hinge face-plate and the hinge face-plate of the doorpost, is painted and finished before the door is hung, and in hanging it the slide which carries the pivot is inserted within the vertical slot of the pillar-plate and secured by a screw in such manner that the end of the slide closes the "ertical slot and forms a part of the face of the pillar-plate. This pillarplate has the same finish and polish as the face of the pillar, and it is found very difficult to polish the end of the slide and the head of the securing-screw to correspond to the polished surface of the pillar-hinge plate after the door is hung. In such operation the polished and finished surface of the pillar plate is often marred and blurred, and especially in this case, when it is found necessary to remove and replace the door by detaching the slide from the face-plate.

The object of my improvement is to avoid the marrin g of the pillar-face in mounting and removing the door. For this purpose I shorten the slide, so that its outer end will not be flush with the polished face of the pillar-plate, and I form the outer surface of said plate with a recessed seat around the outer end of the slide, and secure in such seat, and directly over which makes a cover and a finish for the insertible slide, and when secured serves to bind the slide firmly in a socket-arm of the faceplate and to allow its removal and replacement without marrin g any part of the polished surface of the pillarplate after the door is mounted.

It will be understood that the finishing of the coach-pillars is theimportant-matter in the use of such a hinge, and that it is important in preserving such finish that no part of the insertible slide shall appear in the face of the pillar-plate in hanging the door, for the reason stated that the polished surface of the pillar should not be touched, and all necessity for touching it in any polishing operation in hanging the door is a very serious objection in using such coach-hinges.

Referring to the accompanying drawings, Figure 1 represents a face View of the pillarplate of the Schwind hinge in the open position of the door, and in which 2 indicates the flush end of the insertible slide which carries the pintle of the hinge. Fig. 2 represents a face view of the pillar-plate with the door-hinge part in the open position of the door, and showing the finish cap or cover for the insertible slide which carries the hinge-pintle; Fig. 3, a similar view, the finish cap or cover being removed from the face-plate; Fig. 4, the faceplate, the slide being removed; Fig. 5, a vertical section taken through the line as w of Fig. 2; Fig. 6, the finish-cap; and Fig. 7, the doorhinge part and the slide B, which carries the hinge-pintle.

The construction of the hinge proper is identical with that in the patent referred to, and shown in Fig. 1, my improvement being the addition of a finish cap or cover for concealing the end of the slide which carries the hingepintle.

Of this hinge, A is the plate, which is screwed to the face of the pillar of the coachbody, and is polished and finished with the face of said pillar. b is a socket-arm extending from the rear side of said face-plate.

B is a slide, which is adapted for insertion into the socket of the arm b, and carries the pintle e, by which said slide is secured to a bent arm, e, which is formed with the plate 0 of the door-post. The socket of the arm I) is of dovetail form, and the slide is of corresponding form, so that when inserted it is secured and can only be withdrawn in the direction of its length when the door is hung. The slide may also be of taper form.

The pillar-plate A has a horizontal slot, 0, and a vertical slot, 0, opening therein and into the dovetail-socket of the arm I), as shown in Fig. 4. The slide B is a solid arm, and the pivot e is preferably a rivet-pin formed integral therewith.

In mounting the door the slide is inserted into the arm-socket, carrying the bent arm by its pivot-connection into and through the horizontal slot 0 of the pillar-plate, within which slot the arm moves with the opening and the closing of the door.

Such is the construction of the hinge referred to, the outer end of the slide being formed with an elongated head, 2, which is seated within a recessed seat in the pillar-face plate and secured thereto by a countersunk screw, so as to form a part of the surface of said plate, as shown in Fig. 1.

For the purpose of concealing the insertible slide I cut off its elongated fastening-head z, referred to, and thereby shorten the slide, so

as to bring its outer end within a recess, a,

formed in the face of the pillar-plate A around the end of said slide. The outer end of this slide is formed with a shoulder, 8,. adapted to fit a recess, 1, in the side of the socket'arm and within the recess a, so as to prevent the slide from being too tightly bound when inserted in said socket. This surface-recess to forms a seat for a finish cap or cover, a, which, when fitted therein,closes over and in contact with the head of the slide.

The cap or cover is finished with a polished or silvered face, and is formed with a countersunk hole, a, to receive a screw, v, by which it is secured upon its seat, and in being screwed home it serves to clamp the slide in its socket.

The screw-head is also polished or plated, the same as the finish-cap, and these parts are furnished the trade with the hinge.

I have shown and described the finish-cap as being secured in a recessed seat by a screw; but it is obvious that it may be secured by other means. The slide may also be secured to the socket-arm by a screw independent of the finish-cap, and the latter may be secured in front of the slide without recessing the faceplate, as there is room enough between the hinge-plates for the thickness of the cap when the door is closed. I prefer, however, to secure the finish-cap within a recess, so that it will be flush, or nearly so, with the face-plate.

To remove the door the finish-cap is removed to allow of the withdrawal of the slide, and in again hanging the door the finish-cap is applied over the end of the slide without the least injury to the finish of the pillar-plate.

I claim- 1. In a concealed hinge constructed substantially as described, the combination, with the slide B, which carries the pintle of the hinge, of a separate polished or plated finishcap, u, secured to the pillar-plate A in front of the outer end of said slide, to conceal it, substantially as described.

2. In a concealed hinge substantially such as described, the pillar-plate A, having the recessed seats a and r and the socket-arm b, the shortened slide B, carryingthe hinge-pintle and having the end shoulders, s, incombination with the finish-cap u, the swinging hinge part 0 e, and the cap-securing screw 1), the said finish-cap being arranged within said recess over the shouldered end of the slide, substantially as and for the purpose specified.

In testimony whereof Ihave hereunto set my hand in the presence of two subscribing witnesses.

FRANK P. PFLEGHAR.
